610rwhp 423lbs torque for a VF Stage 3 M3 tuned by OE Tuning is now the world's most powerful supercharged S54. The vehicle was previously running a tune from VF's partner, GIAC, but there were concerns about the car running too lean as well as having idle surge issues which are well documented with VF cars. OE Tuning managed huge gains as well as a safer air fuel ratio from the previous tune.

I've baselined a ton of cars on this dyno, and a local mustang dyno down the street, and a dynojet on the same day. They all read similar, the only thing about the dynapack it reads maybe 1% higher on the torque reading only, probably due to the lack of rear wheels.

It is a non-adjustable dyno (no ctrl x, no temp probe in the engine bay bs), no wheel slippage, no strap bs, weather station attached to machine and cannot be manipulated etc.

Nick @ ACE performance is re-doing the Pulley system on this car to eliminate the idle drag, and the high rpm slippage. He is also going to address the coolant expansion tank which seeps, the SINGLE Bosch 044 fuel pump that ran out of pressure past 7600 rpms and the tiny air filter that was clogged during these pulls. Then we will give it another shot

It was 94.4 degrees during testing that Friday and the humidity was at 100% according to the weather station.

i have some questions regarding the tuning, and im not going into a rant or slamming just really curious. was anything modified from the VF end to complete the outstanding tuning done on this. This appears to be a solid tune and was curious if you removed all the so called "scaling resistors" from the car to tune the DME or are they still in use?

To start out, this car is running an Alpha N.
Next, the rescaling resistor by and of itself isn't going to be the problem.
A rescaling resistor simply acts as a voltage divider when combined with the internal resistance of the ECU's ADC (Analog to Digital Converter) input with respect to signal ground. Generally an ECU ADC input can read from 0 to 5 volts.
But the MAF can put out a voltage WELL above 5v. The rescale resistor simply will (example) cause the ECU to read 5/6ths of the actual MAF voltage - so that 6v out of the MAF becomes 5v into the ECU.

The key is how the TUNE handles this. Is the MAF table properly
rescaled? If so, then the Q (airmass in Kg/Hr) number in the ECU represents the
real world and all is well. If not, "Houston we have a problem".

i was only curious as to what they may or may not have changed in order to tune it properly. i wasnt questioning what would cause a problem or not.

Understand, just wanted to inform you that a resistor is not bad if you have a good tune. It is very obvious that the tune is the weak part of the VF kits.
I am just glad that OE has the ability to get Carbons car running the way it should. Very impressive numbers on pump gas if you ask me.

I'm really starting to think the exact same, the tune deserves way more of the blame. Seems some heat should be directed at GIAC instead of at Nik.

while i do agree with you, im still not 100% there is a tune. i still think they are "tricking" the DME with the resistors and relying on it to adjust and learn on its own to tune the car.

im not sure if you guys remember or not but when the whole F&F thing came out there were several "resistor" mods found readily on ebay, you placed a resistor inline on your Intakes air temperature sensor to trick the cars computer into thinking the air was alot colder causing it to adjust fuel trims and advance timing. well of course they didnt work great and cause a $#@!load of problems, much like what is going on with the VF "tune"

because of there contract with VF and probably signed disclosure statements we will never know or here from GIAC but im pretty sure they just did some small time things like removed some limiters and raised simple things much like the shark injector does.
